Catopocerus
Catopocerus is a genus of small beetles in the family Leiodidae, subfamily Catopocerinae. These beetles are primarily subterranean or cave-dwelling, with reduced eyes and elongated appendages adapted to dark environments. The genus was established by Motschulsky in 1870 and contains species distributed across parts of North America and Eurasia. Members of this genus are among the most troglomorphic beetles in their family.
Nicoletiidae
Nicoletiidae is a family of primitive wingless insects in the order Zygentoma. Members are predominantly subterranean, inhabiting soil, caves, and mesovoid shallow substratum (MSS) environments. Many species exhibit troglobiotic adaptations including lack of eyes and pigmentation. The family contains at least four subfamilies (Atelurinae, Nicoletiinae, Cubacubaninae, Coletiniinae, Subnicoletiinae) with over 100 described genera. Some species are commensals in social insect nests, such as Allotrichotriura saevissima in fire ant nests.
